AWS SageMaker, Azure Machine Learning, and Google Vertex AI carry similar feature breadth and diverging commercial profiles. The platform choice is a commercial choice with technical guard rails.

The buyer side discipline is to compare at workload level. Read the related GenAI vendors practice, the AWS services practice, the Google Cloud services practice, and the GenAI knowledge hub.

Key Takeaways

What a CIO needs to know in 90 seconds

  • Feature breadth converges. All three cover training, inference, MLOps, model registry.
  • Pricing math diverges. Compute, storage, endpoint hosting price differently.
  • Lock in lives in data and pipelines. Not in the modeling code.
  • Training vs inference split matters. Bursty training favors one platform, steady inference another.
  • Negotiation levers are the same as the broader hyperscaler renewal. Commit, scope, term.
  • The credible alternative play applies. Cross hyperscaler ML positioning drives discount lift.
  • Foundation models change the calculus. Bedrock, Azure OpenAI, Vertex Model Garden each carry distinct economics.

Per service pricing benchmark

The three platforms price the core ML services along similar lines. The unit economics diverge at the edges.

Buyer side note

The rate cards converge inside fifteen percent at the headline level. The negotiation leverage lives in committed use discounts, family flexibility, and integration with the broader hyperscaler commit envelope. The platform choice is not driven by per service price.

Feature coverage matrix

The three platforms cover the same modeling workflow. The feature coverage matrix highlights where each platform differentiates.

Feature differentiators

  • SageMaker. Deepest feature breadth, AWS Bedrock integration, JumpStart model hub.
  • Azure ML. Tightest Azure OpenAI integration, Microsoft Fabric data plane, prompt flow.
  • Vertex AI. Strongest unified model garden, Gemini integration, BigQuery native plane.
  • All three. Notebooks, training, hyperparameter tuning, model registry, endpoint hosting, monitoring.

Lock in vectors

Lock in does not live in the modeling code. It lives in the data plane, the pipeline orchestration, and the model registry.

Five lock in vectors

  • Data plane. S3, Azure Data Lake, BigQuery integration depth.
  • Pipeline orchestration. Step Functions, Azure ML pipelines, Vertex pipelines.
  • Model registry. Versioning, lineage, deployment metadata.
  • Foundation model. Bedrock, Azure OpenAI, Vertex Model Garden anchoring.
  • Identity and security. IAM, Entra ID, Google IAM role mappings.

Training vs inference economics

Training and inference carry different commercial profiles. The split shapes the platform choice.

Two economic patterns

  1. Bursty training. Heavy GPU consumption in short windows. Spot pricing and commit pools matter.
  2. Steady inference. Continuous endpoint hosting. Reserved capacity and Savings Plans matter.
  3. Hybrid pattern. Bursty training plus steady inference. Most enterprise patterns sit here.

The hybrid pattern

Most enterprise ML estates run the hybrid pattern. Training cost lives in spot capacity and committed GPU pools. Inference cost lives in reserved endpoints. The buyer side discipline separates the two cost lines and negotiates each line on its own discount instrument.

Negotiation levers

The ML platform negotiation runs through the same five levers as the broader hyperscaler commit conversation.

Five negotiation levers

  • Commit term. Three year deepens the discount.
  • Commit scope. Family flexibility, region flexibility, SKU coverage.
  • Foundation model inclusion. Bedrock, Azure OpenAI, Vertex Gemini inside the commit.
  • Egress envelope. Capped egress or egress credits.
  • Credible alternative. Documented position on a competing platform.

What to do next

The eight step checklist below moves the enterprise from platform sprawl to a documented ML commercial posture.

  1. Baseline the ML estate. Training jobs, endpoints, foundation model calls.
  2. Split the cost. Training, inference, foundation model.
  3. Map portability. Each workload across the three platforms.
  4. Score the TCO. At workload level on each platform.
  5. Identify the commit instrument. EDP, MACC, CUD.
  6. Document the credible alternative. For the upcoming renewal.
  7. Negotiate the commit envelope. With foundation model inclusion.
  8. Stagger the platform renewals. Avoid concurrent expirations.

Frequently asked questions

Which ML platform is cheapest?

None of the three is meaningfully cheapest at the headline rate card. Per service price points converge inside fifteen percent. The commercial difference lives in the discount band, the commit flexibility, the foundation model economics, and the integration with the broader hyperscaler commit envelope. The cheapest platform is the one negotiated best.

Can ML workloads run across multiple platforms?

Yes, with discipline. The lock in lives in the data plane, the pipeline orchestration, and the model registry. The modeling code is portable. The buyer side norm is to keep at least one credible training pipeline and one credible inference workload on a second platform. The discipline anchors the alternative for the commit conversation.

Does the foundation model layer matter?

Yes. Foundation models change the economics. Bedrock, Azure OpenAI, and Vertex Model Garden each carry distinct pricing and bundling rules. The foundation model spend can exceed the underlying compute and storage spend on heavily prompt driven workloads. The commit conversation should include the foundation model line item explicitly.

How much discount lift comes from the credible alternative?

The discount lift on ML platform commits runs twelve to twenty six percent when the credible alternative position is documented. The lift depends on the commit scale, the foundation model envelope, the portability of the workloads, and the strategic value the hyperscaler assigns to the account at renewal.

Are the three platforms genuinely substitutable?

Functionally yes, commercially no. The same modeling workflow runs across all three. The commercial profiles differ. The integration depth into the broader hyperscaler service catalog differs. The platform choice is therefore a commercial choice with technical guard rails, not a pure technology choice.

How should we approach a multi platform ML estate?

The buyer side discipline keeps the heavy training and inference workloads on the primary platform, places one credible workload on a second platform as the alternative anchor, and treats foundation model spend as a separate negotiation line. The discipline produces sustained discount lift across every renewal cycle.

How Redress engages on ML platform commercials

Redress runs the ML platform commercial workstream inside the broader hyperscaler renewal cycle. The engagement baselines the ML estate, splits the cost into training, inference, and foundation model lines, maps portability, scores the TCO, and presents the credible alternative inside the commit conversation.

The engagement is independent. Buyer side. Industry Recognized. Five hundred plus enterprise software engagements. Two billion plus in client spend under advisory.

We split the ML estate into training, inference, and foundation model lines, kept one credible inference workload running on the second platform, and used the documented alternative inside the commit conversation. The platform discount lift landed at twenty one percent and the foundation model envelope came inside the commit.
